Kev Sib Tham Txog Qhov Tseem Ceeb Ntawm Pixel Pitch, Saib nrug deb thiab LED qhia qhov loj me.
LED video phab ntsa txuas txuas ntxiv hloov qhov chaw thoob ntiaj teb.
Cov tsev teev ntuj, cov tsev kawm ntawv, chaw ua haujlwm, tshav dav hlau thiab cov khw muag khoom yog tsim kom muaj kev vam meej, muaj zog, nco txog ntau yam ntawm qhov chaw sab hauv thiab sab nraum zoov.
Yog tias koj tab tom xav txog LED zaub, ib qho ntawm koj qhov kev xaiv tseem ceeb tshaj plaws yog xaiv pixel suab, tab sis koj yuav xav tsis thoob, pixel suab yog dab tsi? Puas yog pixel pitch cuam tshuam tus nqi? Dab tsi yog qhov tseem ceeb thaum xaiv lub suab pixel?
Ntawm no rau tam sim no, CiaYonwaytechsaib seb koj tuaj yeem ua qhov kev xaiv pixel suab zoo rau koj li casLED video phab ntsaqhov project.
Ua ntej, pixel pits yog dab tsi?
LED phab ntsa yog muab tso ua ke tawm ntawm LED panels, uas nyob rau hauv lawv lem muaj ntau LED modules. Cov LED modules no muaj cov pawg LED lossis cov pob LED, xws li liab, xiav thiab ntsuab lub teeb emitting diodes (LEDs) pawg hauv pixels.
Lub pixel suab yog qhov nruab nrab ntawm qhov nruab nrab ntawm ob pixels, feem ntau ntsuas hauv millimeters.
Yog tias koj muaj 10 hli pixel suab, nws txhais tau hais tias qhov kev ncua deb ntawm qhov nruab nrab ntawm ib pixel mus rau qhov chaw ntawm lub pixel uas nyob ib sab yog 10 millimeters.
Qhov thib ob, Dab tsi yog qhov cuam tshuam ntawm pixel pitch ntawm LED zaub duab zoo?
Pixel pitch txiav txim siab LED zaub daws teeb meem, qhov pom qhov tsawg kawg nkaus thiab pom qhov deb ntawm LED screen.
Qhov me me pixel suab, ntau pixel thiab ua rau cov ntsiab lus ntau dua thiab cov duab zoo dua.
Yog li yog tias koj xav tau cov duab daws teeb meem siab lossis yees duab ntawm koj cov zaub, koj xav tau LED zaub nrog me me pixel suab.
Cov duab hauv qab no qhia tau hais tias pixel pitch nyhuv ntawm cov duab zoo, qhov me me pixel ntom ua rau cov kev daws teeb meem siab dua thiab cov ntsiab lus ntxaws ntxiv.
Thirdly, Saib nrug yuav tsum tau txiav txim siab thaum koj tsim ib qho zoo coj zaub.
Pixel pitch ncaj qha txiav txim siab pixel ceev - tus naj npawb ntawm pixels nyob rau hauv ib qho screen muab - thiab pixel ceev ncaj qha txiav txim siab pom kev deb - qhov kev ncua deb ntawm phab ntsa video tus neeg saib yuav tsum muaj kev txaus siab saib.
Qhov zoo dua, lossis me dua, lub suab, qhov ze dua qhov pom qhov deb.
Qhov loj dua lub suab, qhov deb dua tus saib yuav tsum yog.
Pitch tseem cuam tshuam ncaj qha rau tus nqi, tab sis cov pixel loj hauv qhov loj me me coj lub vijtsam thiab saib ntev ntev lossis loj loj coj zaub tab sis qhov pom luv luv ob qho tib si tsis tuaj yeem nqa tawm qhov kev ua yeeb yaj kiab zoo nkauj.
Txhawm rau xaiv qhov zoo tshaj plaws pixel suab ob yam yuav tsum tau txiav txim siab, qhov pom qhov deb thiab qhov xav tau cov duab daws teeb meem.
Me pixel pitches zoo dua txhua lub sijhawm thiab xa koj cov duab zoo dua tab sis, nws raug nqi ntau dua.
Koj tuaj yeem txo cov nuj nqis ntawm LED zaub yuav siv cov pixel loj dua thiab tseem muaj cov duab zoo ib yam yog tias qhov pom qhov deb ntev dua qhov pom qhov deb tshaj plaws.
Qhov kev pom zoo tshaj plaws ntawm pixel pitch yog qhov kev ncua deb uas koj ob lub qhov muag yuav tsis muaj peev xwm mus rau qhov sib txawv ntawm pixel ntxiv yog tias koj mus ntxiv.
Kev suav cov txheej txheem ntawm qhov tsim nyog LED zaub xaiv.
Raws li tau piav qhia saum toj no, pixel suab yog qhov kev txiav txim siab loj rau cov txheej txheem no. Nws mus koom tes nrog lwm yam xws li zaub loj, saib qhov deb, ambient teeb pom kev zoo, huab cua thiab noo noo tiv thaiv, kev sib tw xov xwm, kev xa xov ua haujlwm, duab zoo thiab ntau ntxiv.
Kev siv cov khoom siv LED kom zoo muaj peev xwm ua kom muaj tsheb khiav, txhim kho cov neeg tuaj koom, thiab txhim kho cov neeg siv khoom. Tab sis kev nkag siab yuav ua li cas cov thev naus laus zis yuav cuam tshuam rau ob tus neeg saib thiab koj cov kab hauv qab ua ntej kev nqis peev tuaj yeem pab koj txiav txim siab zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb thiab nyiaj txiag.
Tus qauv kwv yees ntxhib rau koj cov ntaub ntawv raws li hauv qab no:
Yam tsawg kawg saib qhov nrug:
LED zaub screen pom qhov nrug (M) = pixel Pitch (mm) x1000/1000
Qhov zoo tshaj plaws saib nrug:
LED zaub qhov pom qhov zoo tshaj plaws (M) = Pixel Pitch (mm) x 3000 ~ pixel Pitch (mm) / 1000
Qhov kev pom nyob deb tshaj plaws:
Qhov deb tshaj plaws (M) = LED zaub screen qhov siab (m) x 30 npaug
Yog li, piv txwv li, P10 coj zaub nyob rau hauv 10m dav los ntawm 5m qhov siab, qhov zoo tshaj plaws saib nrug yog ntxiv tshaj 10m, tab sis qhov siab tshaj plaws saib qhov deb yog 150meters.
Yog tias koj tsis paub meej txog qhov zoo pixel suab siv rau koj qhov project LED, hu rauYonwaytechLED zaub tam sim no thiab peb mam li taw qhia koj mus rau qhov yog. Rov qab mus ntau zaus rau cov ncauj lus tseem ceeb.
